ENVELOP.

Specification of Letters Patent.

Patented July 9, 1918.

Application filed October 20, 1917. Serial No. 197,704.

To all whom it may concern:

Be it known that I, GEORGE ZERBE, a citizen of the United States,residing at Tiosa, in the county of Fulton and State of Indiana haveinvented certain new and useful Improvements in Envelops, of which thefollowing is a specification.

This invention relates to envelops such as are used in railroad work fortransporting despatches between various departments in an office orbetween various ofiices, requiring no sealing.

This invention contemplates for an object the reinforcing of the scam inthe rear face of the envelop where the greatest wear is caused inopening the envelop for the extraction or replacing of its contents.

Another object of the invention contemplates the provision of an envelopwhich may be manufactured without an appreciable increase in cost overthe style now universally used.

With these and other objects in view the invention consists in theconstruction, combination and arrangement of parts as will behereinafter fully described and claimed Reference is to be had to theaccompanying drawings forming part of this invention, in which likecharacters of reference indicate corresponding parts throughout theseveral views, and in which:

Figure 1 is a rear view of an envelop showing the application of thisinvention,

Fig. 2 is a fragmentary view of an envelop showing detail constructionof the reinforcing member, and

Fig. 3 is a view on the line 3-3 of Fig. 1.

It is the general practice in oflices where it is necessary to transportdespatches from one department to another, and in certain businessesfrom one building to another, not to seal the envelop, but merely tosend it in a packet with others securely bound by a suitable binder.When taking the envelop to remove its contents the operator pulls theback flap away from the front face, causing considerable strain to comeupon the joint formed by the rear andcend flaps, making the life of theenvelop extremely short.

In order to overcome this disadvantage and to increase the life of theenvelop,v I

have devised a reinforcing means, forming an integral part of theenvelop thus reducing the cost of manufacture to a mini mum.

In the drawings 5 indicates the rear flap of an envelop, 6 and 7 the endflaps, 8 the sealingflap and 9 the front face thereof. Each of the endflaps has the free corner extended as at 10 to provide an ear to befolded over the outside of the flap 5 and firmly held in this positionby a suitable adhesive applied to the adjacent side of the car 10.Although I have suggested the use of adhesive to secure the ear to therear of the envelop, it is to be understood that any suitable fasteningmeans, such as an eyelet or the like may be utilized, but the use ofsuch means would of course increase the cost of production of theenvelop. The cars 10 are folded somewhat obliquely with respect to theupper edge of the back of the envelop so that the connection formedbetween the ends and the back may be squarely covered eliminating thepossibility of the ear becoming severed in the manipulation of theenvelop.

The advantages resultant upon the use of my invention will be manifestto all who are conversant with the inconvenience of the devicesheretofore used in the art. Such changes as are permissible by thesubjoined claims may be resorted to without sacrificing any of theprinciple or departing from the spirit of my invention.

Having fully described my invention what I claim as new and novel is:

An envelop of the usual form having the free corners of its triangularend flaps provided with extensions having one of their edges parallelwith one edge of the end flap, and said extensions extending atsubstantially a right angle to the upper edge of said flap, beingadapted to be folded obliquely over the corners of the back flap forreinforcing the seams between the end flaps and back flap.

In testimony whereof I afiix my signature in presence of two witnesses.

GEORGE ZERBE.
